Shielded right-angle panel mount coaxial connector

ABSTRACT

A pair of coaxial cables are interconnected by attaching a tubular sleeve, which extends through and is secured in the wall of a cylindrical collar, to one end of each cable. Electrical connection to the outer conductor braid of each cable is accomplished by sliding a tubular sleeve under the braid, with the bared inner conductor of the cable extending into the center of the associated collar, and crimping a ferrule over the tubular sleeve and braid. A connector body having a center conductor pin dielectrically mounted therein and an open-ended slot through the wall thereof is secured in a panel by a nut having a tubular portion that is coaxial with the pin and also has a slot through the wall thereof. A diagonal groove in one end of the pin is aligned with the slot in the connector body for receiving the inner conductor and tubular sleeve on one cable, respectively, when the associated collar is slid over the slotted end of the connector body. After the inner conductor of the cable is soldered into the pin groove, a cap nut is threaded onto the slotted end of the connector body tightly against the collar to rigidly and nonrotatably secure the one cable in the connector. Similarly, the collar on the other cable is slid over the tubular portion of the nut with the sleeve in the slot thereof and a bent end of the inner conductor of the other cable in a longitudinal hole in the other end of the pin. After this inner conductor is soldered to the other end of the pin, a second cap nut is threaded onto the tubular portion and tightened against the collar to shield this connection of the pin to the second cable.

[57 ABSTRACT A pair of coaxial cables are interconnected by attaching a tubular sleeve, which extends through and is secured in the wall of a cylindrical collar, to one end of each cable. Electrical connection to the outer conductor braid of each cable is accomplished by sliding a tubular sleeve under the braid, with the bared inner conductor of the cable extending into the center of the associated collar, and crimping a ferrule over the tubular sleeve and braid. A connector body having a center conductor pin dielectrically mounted therein and an open-ended slot through the wall thereof is secured in a panel by a nut having a tubular portion that is coaxial with the pin and also has a slot through the wall thereof. A diagonal groove in one end of the pin is aligned with the slot in the connector body for receiving the inner conductor and tubular sleeve on one cable, respectively, when the associated collar is slid over the slotted end of the connector body. After the inner conductor of the cable is soldered into the pin groove, a cap nut is threaded onto the slotted end of the connector body tightly against the collar to rigidly and nonrotatably secure the one cable in the connector. Similarly, the collar on the other cable is slid over the tubular portion of the nut with the sleeve in the slot thereof and a bent end of the inner conductor of the other cable in a longitudinal hole in the other end of the pin. After this inner conductor is soldered to the other end of the pin, a second cap nut is threaded onto the tubular portion and tightened against the collar to shield this connection of the pin to the second cable.

COAXIAL CONNECTOR 1- REFERENCE TO PRIOR APPLICATION This is a continuation-in-part of application of Ser. No. 139,647, filed May 3, 1971 and now abandoned.

BACKGROUND OF THE INVENTION This invention relates to electrical input-output connectors for use in interconnecting two different coaxial cables and more particularly to a right-angle coaxial connector for mounting on a panel and providing shielded connections to coaxial cables.

Telephone and other types of communication systems are designed to operate unattended in the field for extended time periods which may exceed a decade. Such systems may include several electronic equipment packages which are interconnected in the field by coaxial cables. A coaxial cable generally comprises a solid ,or braided inner conductor, a flexible tubular dielectric material surrounding the inner conductor, an outer conductor which is a woven or braided flexible sheath of metallic wires surrounding the dielectric material, and an outer insulating cover. Many different forms of coaxial connectors, including BNC and TNC connectors, have been devised for connecting to coaxial cable. Most of these connectors, however, are not fully satisfactory. Although the connectors may have an acceptable electric characteristic, the mechanical structures thereof are complex and comprise a number of small parts. The procedures for assembling these connectors are therefore complex, time consuming and difficult to perform in the field. Also, the electrical connection in these connectors is made through a pressure contact which may become oxidized and faulty when it is left unattended in the field for an extended time interval.

An alternate prior-art technique for making a permanent electrical connection to a coaxial cable is to separate the braided outer conductor from the cable dielectric over a portion of its length, ravel the braids, and solder them to a ground terminal on an equipment chassis. The inner conductor of the cable is soldered to another terminal on the equipment chassis. A cap is then placed over the junctions of the cable and terminals and soldered to the equipment chassis to provide radio frequency (RF) shielding thereof. This type of connector is unreliable since the braid may fray when the cable is flexed and short circuit the cable. Also, the cap must be unsoldered and removed from the chassis in order to check the connections to the terminals.

An object of this invention is the provision of an improved electrical connector which is simple in structure, may be assembled and connected to a coaxial cable in a relatively short time interval, and includes a soldered connection between the inner conductor of the cable and the center conductor of the connector.

Another object is the provision of a shielded panelmounted right-angle coaxial connector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIG. 1, an electrical connector embodying this invention for interconnecting a pair of coaxial cables comprises an elongated cylindrical body or housing 3 which is norlrotatably secured in the opening 4 of a panel 5 by a nut 6, a pair of adapters 7a and 7b, and a pair of cap nuts 8a and 8b.

The elongated body 3 (see FIG. 2) comprises a rearwardly projecting cylindrical section 10 which is externally threaded for engagement with the similarly threaded bore 11 of nut 6 and a forward projecting cylindrical section 12 which is externally threaded adjacent the end thereof for engagement with the similarly threaded bore (not shown) of cap nut 80. Section 10 has a longitudinal keying flat 14 extending over the length thereof for aligning and preventing rotation of the connector body 3 in the similarly shaped opening 4 which may be stamped in panel 5. The diameter of the keyed section 10 is less thanthat of section 12 to form a shoulder 15 at the junction'thereof which is used as an abutment when the connector is mounted in the panel. The connector body has a first large bore 16 extending over the major portion of the length of section 12 and a second smaller bore 17 extending through section 10 into bore 16. A pair of open-ended slots 18a and 18b are milled through the wall of section 12. A tubular dielectric sleeve 19, which may be made of Teflon, is supported in the bore 17 (see FIG. 3). A center conductor pin 20 is located in the bore in sleeve 19. The pin 20 has a groove 21 milled in one end 200 thereof and a center hole 22 in the other end 20b thereof.

The nut 6 has a lower base portion 27 with an external angularly shaped outer surface and a tubular portion 28 projecting from the base 27. The bore 11 through nut 6 is threaded for engagement with the threads on the body section 10. The flat surfaces 29 of base 27 (see FIG. 4) are oriented for engagemetnt with a wrench for threading nut 6 on the lower body portion 10 and tightening the nut securely against panel 5. The tubular portion 28 also has a pair of open-ended slots 30a and 30b milled through the wall thereof. The circumference of the tubular portion 28 is threaded for engagement with the similarly threaded bore 13 of cap nut 8b. Associated flats 29a and 29b of base 27 are spaced farther apart then the circumference of the tubular portion 28 to provide a shoulder 31.

The adapters 7a and 7b are identical and each cornprises a cylindrical collar 34 having an aperture 35 in one wall thereof for receiving a tubular sleeve 36. The sleeve 36 is oriented in the aperture 35 with its longitudinal axis orthogonal to the longitudinal axis of collar 34 and extends approximately one-quarter of the way into the interior section of the collar 34 (see FIG. Sleeve 36 is rigidly secured to the collar such as by silver solder 37 around the aperture 35. The exterior length of the sleeve 36 is approximately three times the length thereof within the collar. The inner diameter of sleeve 36 is sized for the sleeve to slide smoothly over the tubular dielectric of a coaxial cable to which connection is to be made. The outer diameter of sleeve 36 is slightly less than the width of the slots 18 and 30 in the body section 12 and nut 6, respectively. The inner diameter of collar 34 is sized so that the collar will slide smoothly over the slotted body section 12 and the 'nut portion 28 with the sleeve 36 in a slot 18 or 30. The height of collar 34 is less than that of the slotted body section 12 and nut portion 28 in order to expose threads on which to screw the cap nuts 8a and 8b, respectively.

Prior to the time that is desired to make connections to coaxialcables, the center conductor pin 20 is press fit into the central opening in the dielectric sleeve 19 which is then press fit into the smaller bore 17 of the connector body with a slot 18 and groove 21 in alignment. Each adapter 7 is fabricated by silver soldering a sleeve 36 in the aperture'35 of a collar 34. Assembled connector bodies 3 and adapters 7'are then stored. During fabrication of equipment utilizing the connector, an assembled connector body 3 is preferably rigidly secured in the panel 5 with a nut 6. Alternatively, connector body 3 may be secured in the panel 5 by a conventional nut and lock-washer or a locknut (not shown).

Each of the adapters 7a and 7b is connected to an associated coaxial cable 40a and 40b in the same manner as is illustrated in FIG. 6. The procedure for electrically connecting the adapter 7a to a coaxial cable 40a comprising an outer insulation cover, a braided outer conductor 41a, a tubular'dielectric sleeve 42a, and an inner conductor 43a (see FIG. 6) with a connector embodying this invention is very simple and requires little time. First, a short metal tube or ferrule 44a is slipped onto the coaxial cable 400, and the outer insulation cover is removed from the end of the cable to which connection is to be made. In preparing the cable for connection to adapter 7a, portions of the outer conductor braid 41a and tubular dielectric 42a of the cable are cut back to expose a length of inner conductor 43a which is slightly greater than one-quarter of the diameter of the collar 34. After the outer conductor braid 41a is flaired slightly, the adapter 7a is slid over the dielectric 42a with the sleeve 36a extending under the braid and the bared inner conductor 43a extending a little beyond the center of collar 34a. Ferrule 44a is then slid over the exposed braid 41a and sleeve 36a is crimped with a standard crimping tool (not shown) to rigidly secure and electrically connect the adapter 7a to cable 400 and outer conductor 41a. In this manner, the inner conductor 43a and the braided outer conductor 41a are very effectively separated from each other so that the hairlike strands of the latter cannot cause a short circuit therebetween. Since none of these dimensions are critical and soldering is not required here, the

I aforementioned assembly can be completed in a very short time. The adapter 7b is electrically connected to a coaxial cable 40 b in the same manner except that a length of inner conductor 43b that is approximately one-half the diameter of collar 34b is exposed and a 90 bend is formed in the end of inner conductor 43b.

' 7). Engagement of the end of sleeve 36a in the slot 18 of the body section 12 provides an effective metallic interlock which prevents rotation of cable 400 and bending of the cable adjacent to, and relieves stress at, the connection point of the cable and connector. Adapter 7a effectively holds and aligns the inner conductor 43a in groove 21 while conductor 43a is soldered to pin 20. Cap nut 8a is then screwed onto the protruding threads of the slotted section 12 and tightened against collar 34a to ground the outer conductor 41a of the cable to the panel 5, to rigidly secure the cable 40a in the connector, and to shield the connection. The aforementioned soldering of inner conductor 43a to pin 20 is the onlysoldering operation required while actually making electrical connection of the cable 40a to the connector. Thesolder joint is easily inspected by removing cap nut 8a.

The cable 40b is attached to the connector by=placing collar 34b over the slotted tubular portion 28 of nut 6 with one end of the collarabutting shoulder 31, with the end of sleeve 36b in a slot 30, and with the bent end of inner conductor 43b in the opening 22 of the pin 20 (see FIG. 8). The cable 40b and adapter 7b are held in this position until the end of inner conductor 43b is soldered into the hole 22 in the pin end 20b. Cap nut 8b is then screwed onto the protruding threads of the tubular portion 28 and tightened against collar 34b to ground the outer conductor of cable 40b to the panel 5, to rigidly secure cable 40b to the connector body and to shield the connection thereto. Although the nut 6 is shown in FIG. 1 on a connector body 3 that is designed to receive it, the nut 6 may also be used, together with a collar 7 and cap nut 8, for providing shielded connections to ends of conventional BNC and TNC type coaxial connectors that are normally secured to a panel b a locknut.

An alternate embodiment of this invention that is illustrated in FIG. 10 comprises a connector body or housing 47 having an upper portion-48 that is similar to the body portion 12 in FIG. 1, a lower portion 49 that is similar to the tubular portion 28 of nut 6 in FIG. 1, and an enlarged nut-like section 50 at the junction of body portions 48 and 49. The section 50 has a breadth that is greater than the diameter of the body portions 48 and 49 for providing shoulders that are bearing surfaces. The circumference of body portion 49 is threaded over the major portion of the length thereof for providing threads on which to tighten locknut 38 against panel 5. Each of the body portions 48 and 49 has open-ended slots in the wall thereof for receiving an adapter sleeve 36 and has a circumference and length for receiving an adapter collar 34. The center conductor pin 51 in connector body 47 has grooves in both ends thereof that are aligned with the openended slots in body portions 48 and 49. Thus, adapters 7a which are secured to associated coaxial cables having center conductors that do not have a bend in the end thereof are employed to make electrical connection to both ends of connector body 47.

The connector body 47 is mountedin a panel 5 by inserting the lower body portion in the opening 4 with the lower shoulder of section 50 contacting one side of the panel. The connector body is secured in panel 5 by a lock nut 38 which is threaded onto body portion 49 and tightened against the other side of the panel. Coaxial cables having adapters 7a on one end thereof are attached to the connector body 47 by placing the adapter collars 340 over body portions 48 and 49, soldering associatedinner conductors of the cables in the grooves in opposite ends of pin 51, and threading cap nuts 8 onto exposed threads of body portions 48 and 49 until they abut the associated collars 34a. Alternatively, connector body 47 may be secured in panel 5 by placing an adapter sleeve 36a over body portion 49 so that the sleeve contacts the lower surface of panel 5 and threading a cap nut 8 onto body portion 49 and against the collar, instead of using the locknut 38.

Although this invention is described in relation to a preferred embodiment thereof, modifications of this structure will occur to those skilled in the art. By way of example, the bore 16 of the slotted body section 12 may be threaded instead of the circumference thereof and a collar 34 may be fabricated having a height that is slightly larger than that of the associated section 12. A T-shaped cap having a large diameter section slightly greater than the outer diameter of collar 34 and having a smaller diameter section with the circumference thereof threaded for engagement with the threaded bore of the slotted body section 12 is then employed for rigidly securing the collar in place and a coaxial cable to the connector. In a similar manner, the bore 11 of nut 6 may be threaded over the length of the tubular portion 28 for securing a collar to nut 6 with a T- shaped cap. Alternatively, the collars 7a and 7b may be located in the threaded bores 16 and 11, respectively. The caps 8a and 8b are then screwed into the bores 16 and 11, respectively, to contact the associated collar. Also, when mounting the connector body 3 in an opening in a panel 5, a washer (not shown) may be placed between collar 34a and the bulkhead, or a protruding shoulder (not shown) may be formed on the circumference of the slotted body section 12 adjacent shoulder 15 so that the collar 34a is not in direct contact with the panel. Similarly, a washer (not shown) may be located between nut 6 and the panel. The connector is adapted for receiving different size coaxial cables by fabricating a number of adapters 7 with sleeves 36 having inner and outer diameters related to the diameters of the available cables. The nut 6, adapter 7b, and cap nut 8b may also be used in providing shielded connections of coaxial cables to subpanel ends of conventional coaxial BNC and TNC type connectors that are normally secured in a panel by a locknut. Also, the slots 18 and 30 in the connector body 12 and nut 6, respectively, do not have to be aligned and there may be more than two of either of them. Further, longitudinal holes may be formed in the ends of center conductor pin 51 in FIG. 10 instead of the grooves that are shown.

The scope of this invention is therefore to be determined from the appended claims rather than from the above detailed description.
